Three things: 1) are you trying to fly normally with 3D rates?
2) have you set your radio so that 3D rates are switched on only for 3D maneuvers?
3) what you describe may also be caused by a CG too far aft. Get on or close to the neutral point and you will have that type of response even with moderate elevator throws.
However, if that is the case, it is seldom the aircraft survives long enough to post for an answer. Simply the
truth.
Set up properly you can make an Extra 300 into a violent aerobat or an advanced trainer. Those are the two extremes. There is NO way you can have both on one aircraft.
P.S. As has already been asked, what airframe, wing area, span and all up weight?
All my Airplanes have a CG Slightly back of the CG and I NEVER EVER had an airplane even think about doing a snap, I do understand Aerodynamics pretty well and one wing will not stall faster than the other due to a rearward CG unless 1) Engine Torque is acting on it, or I should say Prop Torque 2) you have a heavy wing or The Airfoils don't exactly Match from wing to wing 3) you have a elevator sevro that is pulling faster or has more throw than the other (dual servos for Elevator) and I have seen the exact same servos new out of the box pull harder than the other 4) Laterial Balance is off.. 5)Wing Insidence is off, it is very possible that this has happened, you have to remember where these things are being built, do you think that they take to time to make sure EVERYTHING is right on when they are mass producing them? I can go On on and on, there are so many different factors to a snap that it is almost imposible to sit on RCU and Guess, the way you find the problem is check EVERYTHING one by one and adjust until you find the Sweet spot. As some people on here say, all airplanes are not created equal.
Alittle more about one wing stalling before the other, IF both wings have the same exact Airfoil and Weigh Exactly the Same, length is the same width is the same, they would stall at the same speed and same Angle of Attack (this is taking out the Torque factor)
A tail heavy CG would have no effect of that, I can get a Nose Heavy Airplane with more throw than a tail-heavy Airplane to throw the tail around faster than a tail-heavy airplane.
